Summary
OpenClaw has a SSRF guard bypass via full-form IPv4-mapped IPv6 (loopback / metadata reachable)
Details
Summary
OpenClaw's SSRF protection could be bypassed using full-form IPv4-mapped IPv6 literals such as 0:0:0:0:0:ffff:7f00:1 (which is 127.0.0.1). This could allow requests that should be blocked (loopback / private network / link-local metadata) to pass the SSRF guard.
- Vulnerable component: SSRF guard (
src/infra/net/ssrf.ts) - Issue type: SSRF protection bypass
Affected Packages / Versions
- Package:
openclaw(npm) - Vulnerable:
<= 2026.2.13 - Patched:
>= 2026.2.14(planned next release)
Details
The SSRF guard's IP classification did not consistently detect private IPv4 addresses when they were embedded in IPv6 using full-form IPv4-mapped IPv6 notation. As a result, inputs like 0:0:0:0:0:ffff:7f00:1 could bypass loopback/private network blocking.
Fix Commit(s)

Release Process Note
This advisory is kept in draft state with the patched version set to the planned next release. Once openclaw@2026.2.14 is published to npm, the only remaining step should be to publish this advisory.
Thanks @yueyueL for reporting.
